13 To create an input device on the :ref:`default_display`:
18 …lv_indev_t * indev = lv_indev_create();        /* Create input device connected to Default Display…
19     lv_indev_set_type(indev, LV_INDEV_TYPE_...);   /* Touch pad is a pointer-like device. */
23 to the display your input device is "connected to" before making the above calls.
33 report the current state of an input device to LVGL.
41 category.  Here is an example of a simple input-device Read Callback function:
124 prevent LVGL sending further input-device-related events.
131 A "Crown" is a rotary device typically found on smart watches.
138 an extension of the pointer input device.  Just set ``data->diff`` to the number of

238 - Register a Read Callback function for your device and set its type to
242 - Assign the group to an input device: :cpp:expr:`lv_indev_set_group(indev, g)`.
263 A common example of an encoder is a device with a turning knob that tells the hosting
264 device *when* the knob is being turned, and *in which direction*.
312 You need to associate an input device with a group.  An input device can

325 To associate a group with an input device use :cpp:expr:`lv_indev_set_group(indev, g)`.
506 - ``read_timer`` pointer to the ``lv_timer`` which reads the input device. Its parameters
525 To solve this you can write an event driven driver for your input device

536 need more control over when to read the input device. For example, you
543    /* Update the input device's running mode to LV_INDEV_MODE_EVENT */
548    /* Call this anywhere you want to read the input device */
